THERMAL DESORPTION SPECTROMETER TDS 40A1 & POWER SUPPLY SET

incl. VAT, plus shipping

Delivery Time 2 - 3 Weeks

The TDS 40A1 is designed for Temperature Programmed Desorption (TPD) applications, also known as Thermal Desorption Spectroscopy (TDS).

 

TPD involves heating a sample under UHV conditions and simultaneously measuring a number of desorbing gas species as a function of sample temperature. A custom designed conical sampling end piece ensures the best possible response to desorbing species.

HEAT3-PS

SAMPLE HEATING POWER SUPPLY

 

DESCRIPTION

The HEAT3-PS is used for resistive heating or electron bombardment heating. The power supply can also be used for effusion cell evaporators. The unit is equipped with a PID temperature controller.

Ramp heating function control sample temperature to protect sample from damage. Sample overheating can also be protected by setting the voltage and current limits. The unit can be operated in auto mode (with temperature control) or manual mode (without temperature control). The unit is equipped with autosave function (the device saves your parameters, pre-set and apply them automatically after restart).

 

FEATURES

Dual heating mode: resistive and electron bombardment

Wide range temperature measurement (1.4 - 2473.15 K)

2D real time chart module

High efficency

Setpoint based over-voltage and over-current output protection

Fully manual or PID temperature controlled (by setpoint and ramp)

Process temperature control with built-in PID controller (with autotuning function for optimized process PID parameters)

Various kind of temperature sensors: thermocouples K/C/

E/N (other on request), Pt, diode

Multiple I/O (10 digital/4 analog) - individual reprogrammable

High resolution (16-bit analog I/O, 0.1 K temp.)

One vacuum channel for active gauges

Shutter control function - up to 2* shutters (e.g. shutters of sources or manipulators)

Mobile solutions for remote access and control

Customised menu options (for robust and effectivity)

Support (easy firmware update via USB)

*for double DC module version, 1 shutter per channel

 

OPTIONS

Second DC module available: two resistive heating zones with independent control, or one resistive heating zone with higher output power (90V, 17A or 45V, 30A) excluding EB module

Analog I/O card for vacuum measurement (1 gauge)
